WebMar 3, 2024 · A logistic regression model is almost identical to a linear regression model i.e. there are weights and bias matrices, and the output is obtained using simple matrix operations (pred = x @ w.t() + b). Just as we did with linear regression, we can use nn.Linear to create the model instead of defining and initializing the matrices manually. WebStep-by-step explanation. The logistic regression analysis was conducted to examine the relationship between gender (Male = 1, Female = 0) and the dependent variable. The model yielded an R-squared value of 0.05104, indicating that the model explained approximately 5.104% of the variance in the dependent variable.
